Agro-based and mineral-based industries MCQ - Practice Questions with Answers

Agro-based industries use agricultural produce as their main raw material. Dal mills depend on pulses, rice mills process paddy, and the cotton industry uses cotton grown in agricultural fields. The iron and steel industry, in contrast, is a mineral- and metal-based industry. It depends on iron ore, coal, limestone and related industrial inputs, not on farm produce. Therefore, among the given choices, iron and steel industry is the one that is not agro-based in Rajasthan.

Khetri Copper Complex is associated with the Khetri copper belt in Rajasthan and is located in Jhunjhunu district, not in Bikaner district. That makes the Bikaner statement the incorrect one asked for in the stem. The complex is treated as an integrated copper mining and refining unit, and the Khetri and Kolihan mines are linked with its ore supply. The complex is also known for associated sulphuric acid and fertiliser facilities, which use by-products from copper processing.

Agro-based industries depend on agricultural or allied raw materials. Textiles can be linked with cotton and other fibres, and leather is commonly grouped with agro-allied activities because it depends on livestock-based raw material. Rubber is also treated as an agro-based raw material in the broad industrial classification. Cement, however, depends mainly on minerals such as limestone, gypsum and other inorganic inputs. In Rajasthan's industrial classification, cement is mineral-based, not agro-based, so it is the item that does not belong.
